Im In a 1st Year University math class and its been a while since i did this stuff and cant remember if im doing this question right so any help would be much appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

The question is to find all the info from the equation y=2(x-4)^2-3

I used the b+/- b^2 -4ac... equation and ended up getting 16+/- square root of 24/4.

This gives an odd number (5.22474, 2.77525) so i dont think it is right. When i apart the original equation to make into ax^2+bx+c=0 form i did 2(x^2-8x+16)-3=0 and i am not sure if that is correct either or if it should be multiplies without brackets.

Thanks for any help
